Title: Electrically conductive stripe
IPC: H01L21/00
Filed: 1970-01-01
Abstract: 1279741 Semi-conductor devices; printed circuits INTERNATIONAL BUSINESS MACHINES CORP 1 Jan 1970 [15 Jan 1969] 136/70 Headings H1K and H1R [Also in Division C7] A conductive track on a substrate consists of aluminium alloyed with copper which acts to reduce current-induced mass transport therein. The tracks may function as electrodes of electronic devices or as interconnections in hybrid thin film circuits, or on passivated chips. A typical use is to form a pattern of multi-layer interconnections between junction-isolated components formed by diffusion into a silicon chip utilizing alumina, silica or silicon nitride as passivating and inter-layer insulation. The tracks may be etched using photoresist techniques from films deposited by vacuum evaporation or RF sputtering, the aluminium and copper being derived from a common or from separate sources. A preferred method is to deposit a sequence of thin layers Al-Cu-Al. Distribution of the copper is improved by depositing with the substrate maintained at a high temperature, or by subsequent annealing at 250-560 C. To retard alloying to the silicon within apertures in the passivation 3% by weight of silicon may be added to the aluminium alloy and adhesion improved by varying the amount of copper throughout the thickness so that the aluminium is substantially free of copper adjacent the silicon. Mechanical strength can be improved by addition of 0À1-0À25% chromium, the consequent reduction in corrosion resistance being minimized by use of a protective coating of pure aluminium. The effect of the amount of copper (preferred range being 0À1-10%), annealing temperature and time on the median lifetime of the tracks is discussed in detail. Use of specific copper-aluminium alloys which also contain one or more of manganese, magnesium, chromium and silicon is suggested.

Title: Improvements in the manufacture and production of anthanthrone derivatives
IPC: C09B3/68
Filed: 1928-10-09
Abstract: 327,712. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Oct. 9, 1928. Divided on 325,797. Anthanthrone derivatives are prepared by condensing diaminoanthanthrones with organic compounds containing at least one negative substituent, preferably in organic solvents of high boiling point, acid-fixing agents and/or condensing catalysts being added, if desired. Such organic compounds comprise aliphatic, isocyclic, heterocyclic or cycloaliphatic substances containing a negative substituent such as halogen or a nitro group. Soluble solvents are nitrobenzene, naphthalene, and suitable catalysts, copper, aluminium, mercury, or a compound or salt thereof such as an oxide or carbonate. According to examples a diaminoanthanthrone is condensed with benzoyl chloride (dyes wine-red to rose-red shades), m-methoxybenzoyl chloride, 1-chloranthraquinone (dyes grey shades) and 1-aminoanthraquinone-2-carboxylic acid chloride (dyes blue-red shades). The aminoanthanthrones are prepared either by direct nitration of anthanthrone, a dinitro derivative being obtained by dissolving anthanthrone in nitric acid, or by nitrating 1.1<1>-dinaphthyl-8.8<1>-dicarboxylic acid and converting this to the dinitroanthanthrone with acid condensing agents, followed by reduction. A modification of the latter method consists in converting nitronaphthostyril to 1-amino-4-nitronaphthalene-8-carboxylic acid by alkali treatment, and the latter diazotized and heated with ammoniacal cuprous oxide to give 1.1<1>-dinaphthyl- 4,4<1>-dinitro-8.8<1>-dicarboxylic acid which is then treated as above. Specifications 285,502, 307,364, 307,947 and 318,180 are referred to.

Title: Improvements in or relating to means for the regulation of the speed of electric motors
IPC: H02P7/26
Filed: 1945-01-03
Abstract: 601,673. Automatic control systems for electric motors. APPLICATIONS MECANIQUES ET ELECTROTECHNIQUES APLEC SOC. ANON. Jan. 3, 1945, No. 251. Convention date, Dec. 11, 1943. [Class 38 (iv)] In a speed control system for electric motors, the supply circuit includes at least one electronic relay, the grid voltage of which is the difference between two D.C. voltages, one of constant value and the other a function of motor speed. In Fig. 2, D.C. motor 1 is supplied through electronic relay 4 and transformer 3 from source 2. The grid 7 of the relay is biassed by battery 9, associated with potentiometer 10, and tachometer dynamo 8. The potentials of battery 9 and generator 8 are in opposition and so connected that grid 7 becomes more negative with rising motor speed until, at a speed determined by the setting of potentiometer 10 the relay ceases to conduct with a consequent drop in motor speed until the generated e.m.f. of 8 is reduced to a value at which 4 again conducts. With large motors the supply may be passed through a number of electronic relays in parallel or part only of the load current may be passed through the relay. In Fig. 4 A.C. motor 31 is supplied by alternator 27, driven by motor 1. The speed of 31 is stabilized as motor 1 is subjected to the same control as in the first embodiment. In a further example an A.C. motor is connected to the supply in series with the primary winding of a transformer, the secondary of which is short-circuited by two electronic relays, grid controlled as in Fig. 2 to vary the conductance of the primary and consequently the voltage applied to the motor. In the Fig. 2 arrangement the motor 1 may be supplied directly from the mains without a transformer 3 while additional speed control is effected by the field excitation of tachometer 8.

Abstract: 995,318. Automatic temperature control. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 26, 1964 [Jan. 2, 19631, No. 270/63. Heading G3R. The temperature of an electric heater H is maintained constant by producing a signal representative of its electrical resistance during recurrent measuring time intervals and using each of these signals to control the current supplied to the heater during a succeeding supply time interval, the current supplied to the heater during the measuring intervals always being adjusted to a common value. The heater H is arranged in a bridge circuit and an alteration in its resistance due to a variation in its temperature will produce a signal during a measuring interval which is stored and used to control, during the succeeding- supply interval, a regulator by way of a phase control circuit. The supply of current to the heater H during each measuring interval is adjusted to the common value by means of a standard generator SSG. The regulator may comprise silicon controlled rectifiers, thyratrons on saturable reactors which may to regulated during the measuring intervals to pass full half cycles of current to the heater.

Title: Electro-mechanical servo arrangements
Inventor: SUMMERLIN FREDERICK ARTHUR
IPC: G05D1/08
Filed: 1959-01-02
Abstract: 937,821. Automatic steering control. SPERRY GYROSCOPE CO. Ltd. Jan. 4, 1960 [Jan. 2, 1959], No. 275/59. Class 38 (4). In a system for automatically controlling a variable, electrical signal generating means normally apply equal signals, in response to changes of the variable, to two identical control channels the mechanical outputs of which are applied to a comparator and also to a mechanical differential the output of which is representative of the average of the inputs. As shown, electric signals from duplicate instruments of an aircraft automatic pilot control, through amplifiers 18 and 19, electro-mechanical actuators 20 and 21 operating on a linkage 11, movement of the output element 10 of which is equal to the mean of the two input movements. This movement is applied through a further linkage 8 to control a fluid-pressure servo-system 5 operating an aircraft control surface. Follow-up signals from potentiometers 16 and 17 operated by servo-system 5 are applied to the inputs of amplifiers 18 and 19. Automatic control may be overridden by operation of a manual lever 2 which operates on linkage 8 through a further linkage 22 provided with mechanical follow-up through an element 24. Such manual actuation overcomes the effect of a yieldable clamp which otherwise holds the output element of linkage 22 so that lever 2 follows movements of the control surface during automatic control. If the operation of e.g. a switch 32, due to a predetermined difference between the displacements of the two actuators 20, 21, indicates that one of the channels is defective, a switch (not shown) may be operated manually or automatically to clamp the appropriate end of linkage 11 and double the amplification in the working channel. The switch referred to may render both channels inoperative. Specification 859,792 is referred to.

Title: Power operated fastener tool
IPC: B25B23/145
Filed: 1972-01-04
Abstract: 1367201 Power tools ROCKWELL INTERNATIONAL CORP 4 Jan 1972 [6 Jan 1971] 284/72 Heading B3N A power operated tool comprises a motor 22, an output member and means intermediate the motor and the output member operable beginning with the exertion of a rotation resisting force by a fastener being tightened to absorb kinetic energy from a rotating component or components to prevent said kinetic energy from being transmitted to and thereby overtightening a fastener. The absorption means is a spring 102 that connects driven member 94 to output member 114 via members 98 and 108. Thus as the spring is wound, it exerts an increasing force on said component or components to reduce the speed of rotation of and thereby convert the kinetic energy of the component or components. The absorbing capacity of the spring at least equals the kinetic energy of the motor at no-load speed. As shown the tool has a valve 56 by which the torque output of the tool can be controlled. The valve has a shaft extending forwardly to portion 148. A pawl 150 is spring biased against portion 148. Member 98 forms a cam having a follower 168 that is in engagement with the pawl. During operation member 98 rotates relative to member 114 to which the pawl is connected. When the high point of the cam co-operates with the follower the pawl is pivoted downwardly thus releasing shaft portion 148. Due to a pressure differential across valve 56 the valve is caused to shut. The start positions of the follower and cam can be adjusted by means of adjusting mechanism 120. An epicyclic gear connects the motor to member 94. Fig. 5 shows a device incorporating energy absorbing springs 214, which device can be connected to the output member of a power tool. Fig. 7 shows a tool incorporating a clock spring 214a as shown in the embodiment of Fig. 5. Valve 56a is operated through an actuator 232. During operation the actuator is caused to rotate by pin 244, the position of which is controlled by axial movement of operator member 234. Movement of member 234 is caused by relative rotational movement between output member 212a and member 234 that is connected to member 94a. After a fastening operation the spring returns the components to their original positions by reverse rotation of the rotor of the motor.

Abstract: 718,798. Garage lifts; hydraulic jacks. BAUWENS, A. Jan. 7, 1953, [Jan. 7, 1952.] No. 498/53. Class 78 (3). In a hydraulic ram, particularly for operating garage lifts, a curved T-shape plate 5 first slowly throttles and then almost closes the inlet and outlet port 4 as the piston 2 moves into its uppermost position and then, after the maximum closure has been attained, allows the piston to make a further slight upward movement. A rod 6, which is slidably mounted in a block 7, supports the plate 5 at one end and is engaged at its other by a projection 9 when the piston nears the end of its upward stroke. The plate 5 is slightly spaced from the cylinder wall, so that it never completly closes the port 4 and is so shaped that when the ram is lowered the pressure of the exhausting fluid retains the plate in its raised position so damping the lowering movement, but if it is desired to increase the rate of lowering, a brief interruption of the exhaust flow allows the rod and plate to drop so opening port 4. The piston which is a loose fit in the cylinder i is guided by stationary cross arms 3 which also constitute movement limiting stops.
